SABS or SANS standard 1123 are flanges developed for use in high pressure environments. Typically produced from stainless steel, these international standards are applied in the fields of water. Hence, the SANS / SABS 1123 Flanges may also be used in applications involving sanitation.
SABS (South African Bureau of Standards) and SANS (South African National Standards) 1123 flanges are a set of standards and specifications for flanges used in various industrial applications in South Africa. These standards are designed to ensure the quality, compatibility, and safety of flanges used in piping systems.

SABS / SANS 1123 Flanges Exporter
Manufacturer and Exporter of SABS / SANS 1123 Flanges in Dimension accordance with ANSI/ASME B16.5, B 16.47 Series A & B, B16.48, BS4504, BS 10, EN-1092-1, DIN, etc. Certified with NACE, PWHT, HIC, SSC, Magnetic Particle Test, Dye Penereteration Test etc.
Purpose and Scope:
SABS/SANS 1123 standards are developed to provide guidelines for the manufacturing and use of flanges in South Africa.
These standards cover a wide range of flange types, sizes, and pressure ratings, catering to different industrial needs.
Types of Flanges:
SABS/SANS 1123 includes specifications for various types of flanges, such as welding neck flanges, slip-on flanges, threaded flanges, and blind flanges.
Different flange types serve specific purposes in piping systems, and their designs are standardized to ensure interchangeability.
Materials and Dimensions:
The standards provide specifications for the materials used in the construction of flanges. Common materials include carbon steel, stainless steel, and alloy steel.
Dimensions, including the diameter, thickness, and bolt hole patterns, are outlined to ensure uniformity and compatibility with other components in the piping system.
Pressure Ratings:
SABS/SANS 1123 defines pressure classes or ratings that indicate the maximum pressure a flange can withstand under specific operating conditions.
Pressure ratings help in selecting the appropriate flange for a given application, considering factors like fluid pressure and temperature.
Marking and Identification:
Flanges manufactured in compliance with SABS/SANS 1123 standards are typically marked with relevant information, such as the standard number, material grade, and manufacturer's identification.
Proper marking ensures traceability and helps in quality control.
Testing and Certification:
Flanges produced according to SABS/SANS 1123 undergo various quality control tests, including dimensional checks, material testing, and pressure testing.
Certification is provided to products that meet the specified standards, giving confidence to end-users regarding the reliability of the flanges.
